A strong and permanent upward trend which has been observed for years in the scope of coke quality expectations of its recipients can be referred to the use of its substitutes in the BF process. Meeting those expectations is especially difficult under the domestic conditions which are characterized by limited resources of high quality hard-type coking coals. This situation leads to a growing interest in solutions which enable the production of high quality coke based on coal blends which contain a lower share of hard-type coking coals (stamping technologies, briquetting, oiling or pre-heating of the coal blend, optimization of coal blends grain size distribution, and coke dry quenching). In the meantime, the domestic coke plants are using a permanently growing amount of foreign coking coals, including sea-born coals. Equity changes which aimed at forming a vertically integrated Coal - Coke Group comprising Jastrzębska Spółka Węglowa S.A., Koksownia "Przyjaźń" Sp. z o.o. and Kombinat Koksochemiczny "Zabrze" S.A. are limiting the access of ArcelorMittal Poland S.A. coke plants to the best domestic type 35 coking coals. The steadily increasing coke quality expectations of the coke recipients as well as the necessity to maintain price competitiveness led the Coke Plant Zdzieszowice to extend its raw materials base which now includes also imported coals. Furthermore, an increase in the share of semi-soft type coking coals in the coal blends is considered by implementing a technology already known but not used in the domestic cokemaking industry, i.e. the coal blend pre-heating technology. The ArcelorMittal Poland S.A. Zdzieszowice Plant, as the biggest consumer of foreign coking coals, especially sea-born coals, has a broad experience in using those coals in the production of high quality metallurgical coke. The Site has developed and implemented procedures which enable the composition of coal blends and their safe processing into high quality coke. Among many coal blend preparation technologies, the implementation of coal blend pre-heating technology is considered. By maintaining the quality of the produced coke this solution should enable a further reduction of the domestic hard-type coking coals share in the coal blends by their substitution with semi-soft type coking coals. This article which continues the topic of the tests presented last year (1), concerns the comparison of the effects of coal blend pre-drying executed for two kinds of coal blends used in the Coke Plant Zdzieszowice. One of the coal blends was composed of domestic coals only while the other one included also imported coals. As the effect of the pre-drying the possibility of increasing the share of semi soft type coking coals in the coal blends has been assumed while simultaneously maintaining the previous quality of the produced coke.
